14248996 - This is Messier 1, the first entry in Charles Messier's 18th century catalogue of deep-sky objects that were not to be mistaken for comets, his real quest. It is also NGC 1952, or the Crab Nebula, from the Earl of Rosse's 19th century description and naming. It is north of the lower horn of Taurus the Bull. This is a remnant cloud of debris expanding away from a supernova explosion that was witnessed in 1054 CE. All that's left of the progeniitor star now is a neutron star forming a spinning pulsar at the heart of the explosion debris. Some red H-alpha tendrils are obvious around the extremity
